Chromones and Pyrazole derivatives were reported wide range of biological activities. Hence, it was planned to synthesize and screen for their antibacterial (in vitro) activity. A series of novel 2-acetyl-4-chlorophenyl pentafluorobenzoate derivatives were synthesized and evaluated for in-vitro antibacterial activity. Chromones and Pyrazole derivatives like 6-chloro-2-(pentafluorophenyl)-4H-chromen-4-one, 4-chloro-2-[5-(pentafluorophenyl)-1H-pyrazol-3-yl]phenol were synthesized by a sequence of

Antibacterial activities of chromones derivatives, Pyrazole derivatives were tested by the disc diffusion method by using Mueller Hinton Agar (M173) medium against various microorganisms such as Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli and Pseudomonas aeruginosa. Gentamycin at 100μg/ml was used as standard drugs for antibacterial. Characterization of all the compounds were performed by IR, 1H NMR and Mass spectroscopy. The anti-inflammatory data suggested that compounds BC, BD and BE showed significant activity. The compounds bearing nitro and oxygen groups have shown prominent activity when compared to compounds without these groups.
